Although parrot species are infrequently infected by hemoparasites in the wild, some fatal infections have been reported in captive individuals. Conversely birds of prey are frequently infected by hemoparasites. In this study, 193 captive birds from Convention on International Trade in Endangered...

Parasitic infections are widespread among reptiles and may cause serious problems. Any data on its prevalence may be useful for their health management in captivity. Hence, a survey through faecal sample examination was conducted to assess the helminth fauna in captive reptiles [Caiman crocodile (...

Background: Parasites can exert selection pressure on their hosts through effects on survival, on reproductive success, on sexually selected ornament, with important ecological and evolutionary consequences, such as changes in population viability. Consequently, hemoparasites have become the focus...

Ascaridiasis by Ascaridia hermaphrodita is a common parasitic disease in blue-fronted Amazon parrots (Amazona aestiva) and the contamination occurs by ingestion of eggs. Illegal trade of wild birds can increase the frequency of visceral erratic migration by this parasite. Hence, this report...

Reptiles and amphibians are becoming increasingly more common in the exotic pet trade and as such veterinary care is also rising. Parasitic infections can pose a serious threat to pet reptiles and amphibians and are a common finding in these exotic pets. The purpose of the present study was to...

Amazona aestiva is a species with great representativeness at the Centro de Triagem de Animais Silvestres (CETAS-RJ). Parasitic infections are some of the primary health problems found in wild birds that are kept in captivity. The objective of this study was to describe the prevalence and intensity ...

Angiostrongylus cantonensis is an invasive zoonotic nematode which causes eosinophilic meningitis in accidental hosts - vertebrates including humans - and is known to impact wildlife. Even though the parasite originates in Southeast Asia, it has spread worldwide, especially into fragile island...

Parasites have evolved a diversity of lifestyles that exploit the biology of their hosts. Some nematodes that parasitize mammals pass via the placenta or milk from one host to another. Similar cases of vertical transmission have never been reported in avian and nonavian reptiles, suggesting that...

Dispharynx nasuta is a widespread nematode parasite located in the proventriculus. This parasite may cause mortality in free-living birds or in captivity. However, reports of this parasite in psittacines are scarce. In a private aviary, in Zamora, Michoacan, Mexico six red-rumped parrots (Psephotus ...

Parasites interact with nearly all free-living organisms and can impose substantial fitness costs by reducing host survival, mating success, and fecundity. Parasites may also indirectly affect host fitness by reducing growth and performance. However, experimentally characterizing these costs of...
